The dollar is a special symbol and we use it for using variables inside the quotation marks.

String currency="ruppee"; 
Text('Indian currency is ${currency}');

so if we want to save the dollar symbol in string type we need to add / like this

String symbol = "\$";

Now we can use it as a string.

If you have an amount inside a variable and you want to display it with the dollar sign, do this.

void main() {
  double amount = 49.99;
  print('\$ ${amount}');
}

Output: $ 49.99

Just put \$ and then works.

Text('\$800') = $800

Besides using a backslash in front of the dollar sign, you can also use a "raw string":

r'! @ # $ & * ~'

The "r" prefix indicates that dollar is no longer a special character.

Dollar is a special character, you need to banalize them with a \ 

void main(){
    String s = "! @ # \$ & * ~";
    print('$s');
}

The reason this is not working for you is because the dollar sign $ is used for template literals, which can be used to "interpolate the value of Dart expressions within strings".
When only evaluating identifiers, just a dollar sign followed by the variable name is enough: 'foo: $foo'
However, curly braces can be added to evaluate whole expressions: 'foo * bar: ${foo * bar}'

Having said that, you will need to escape the dollar sign using a backslash: '50\$'

For your example: Text('! @ # \$ & * ~', style: TextStyle(color: Colors.grey))
